辽宁省装备制造业效率分析

运用2001—2014年27个省市的面板数据,使用DEA模型中的BCC模型和Malmquist指数法对辽宁省装备制造业及其细分行业的综合效率和全要素生产率(TFP)变化进行分析。结果表明:辽宁省装备制造业更多依靠规模和数量取胜,而非产业发展质量; 近几年来辽宁省的要素使用效率有一定的提升,对劳动投入的利用水平低于资金投入; 辽宁省装备制造业全要素生产率的变动主要是由技术进步引起的,技术效率的变动起的作用相对较小,但近几年全要素生产率的下降则主要是由技术效率变动的下降引起的,而这种下降主要是由于纯技术效率的下降引起的。

Analysis on efficiency of equipment manufacturing in Liaoning Province: based on DEA model and Malmquist index method

Drawing on the panel data of 27 provinces, municipalities and autonomous regions from 2001 to 2014, the overall efficiency and total factor productivity(TFP)change of equipment manufacturing industry and its sub-sectors in Liaoning are analyzed by using BCC model in DEA model and Malmquist index method. The results show that the performance of the equipment manufacturing industry in Liaoning depends more on the scale and quantity, rather than the quality of industrial development; the efficiency of utilizing factors in Liaoning has a certain degree of upgrade in recent years, but the level of utilization of labor input is less than capital investment; the changes of TFP in Liaoning equipment manufacturing industry is mainly caused by technological advances, and technical efficiency plays a relatively minor role; but the decline of TFP in recent years is mainly caused by the decline of technical efficiency, whose decline is mainly due to the decline of pure technical efficiency.
